摘　　要：在电解铝生产过程中,会产生大量有害烟气,这种气体严重危害人类的健康,破坏生态环境。本文针对电解铝生产过程,研发了"CC"烟气净化控制技术。结合电解铝烟气净化工艺过程,在生产安全稳定的前提下,以提高粉尘排放指标合格率以及总氟排放指标合格率为优化控制的目标,采用前馈与反馈相结合的优化控制方法,提高电解烟气净化指标,解决铝电解产生的环境污染问题。During aluminum reduction, a larger harmful fume generates, which is harmful to human health and destroys ecological environment. For the problems from aluminum reduction production, the control technology of Circle -centre （CC） pot fume scrubbing is developed. Improving qualified rate of dust emission index and total fluorine emission are taken as an optimal control goal under safe and stable production combing with pot fume scrubbing process, optimal control method of combining feedforward with feedback is used for the technology to improve the pot fume scrubbing index so as to solve the problem of environmental pollution from aluminum reduction.
